👀 SPOILER-FREE SUMMARY

A classic Detective Conan school mystery kicks off with an unsettling discovery that turns an ordinary day into a full-blown investigation. The episode introduces Rumi Wakasa, a new assistant homeroom teacher whose presence immediately shifts the dynamic around Conan and the Detective Boys. Expect a slower, more deliberate pace here — this is a setup episode that prioritizes atmosphere and clue-laying over action. The tone leans into genuine suspense as a decade-old skeleton found in an abandoned storage shed raises questions that won't be answered quickly. The Detective Boys get solid screen time working as a unit, and Conan's sharp instincts are on full display as he starts piecing together what everyone else overlooks. A strong opening chapter that rewards patient, detail-oriented viewers who enjoy classic whodunit storytelling.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Rumi Wakasa Arrives

The Detective Boys meet their new assistant homeroom teacher, Rumi Wakasa, whose seemingly mild-mannered demeanor and odd request to retrieve quicklime from an old storage shed immediately sets the stage for something deeper.

Skeleton in the Shed

While searching the dilapidated storage shed, Conan and the kids stumble upon a human skeleton alongside a mysterious scroll — turning a simple errand into a full-blown crime scene.

Conan's Ten-Year Flashback

Conan recalls a memory from his time at Teitan Elementary a decade earlier, providing critical context that links the skeleton to a major unsolved robbery involving 200 million yen in gold ingots.

The Gold Heist Connection

Details of the decade-old robbery surface as Conan pieces together the scroll's significance and the skeleton's identity, suggesting the shed served as a hiding spot — or a grave — for someone involved in the heist.

The Shed Was Tampered With

Conan and the group realize the storage shed has been disturbed since their initial visit, meaning someone else knows about the skeleton and may be actively covering their tracks — or watching them.

📍 ARC CONTEXT

This episode pivots from the high-energy 'Kaito Kid and the Trick Box' two-parter into a grounded, school-set mystery, offering a tonal shift that keeps the series rhythm fresh. It serves as part one of a two-part arc, establishing the skeleton case and introducing Rumi Wakasa, whose role adds a new layer of intrigue heading into episode 890. For long-running Conan fans, this marks another canon entry that expands the supporting cast while delivering the investigative fundamentals the series is built on.
